From source file:com.ferdi2005.secondgram.support.widget.RecyclerView.java

/**
 * Since RecyclerView is a collection ViewGroup that includes virtual children (items that are
 * in the Adapter but not visible in the UI), it employs a more involved focus search strategy
 * that differs from other ViewGroups.//w  ww. j a  va 2  s  .  c  o m
 * <p>
 * It first does a focus search within the RecyclerView. If this search finds a View that is in
 * the focus direction with respect to the currently focused View, RecyclerView returns that
 * child as the next focus target. When it cannot find such child, it calls
 * {@link LayoutManager#onFocusSearchFailed(View, int, Recycler, State)} to layout more Views
 * in the focus search direction. If LayoutManager adds a View that matches the
 * focus search criteria, it will be returned as the focus search result. Otherwise,
 * RecyclerView will call parent to handle the focus search like a regular ViewGroup.
 * <p>
 * When the direction is {@link View#FOCUS_FORWARD} or {@link View#FOCUS_BACKWARD}, a View that
 * is not in the focus direction is still valid focus target which may not be the desired
 * behavior if the Adapter has more children in the focus direction. To handle this case,
 * RecyclerView converts the focus direction to an absolute direction and makes a preliminary
 * focus search in that direction. If there are no Views to gain focus, it will call
 * {@link LayoutManager#onFocusSearchFailed(View, int, Recycler, State)} before running a
 * focus search with the original (relative) direction. This allows RecyclerView to provide
 * better candidates to the focus search while still allowing the view system to take focus from
 * the RecyclerView and give it to a more suitable child if such child exists.
 *
 * @param focused The view that currently has focus
 * @param direction One of {@link View#FOCUS_UP}, {@link View#FOCUS_DOWN},
 * {@link View#FOCUS_LEFT}, {@link View#FOCUS_RIGHT}, {@link View#FOCUS_FORWARD},
 * {@link View#FOCUS_BACKWARD} or 0 for not applicable.
 *
 * @return A new View that can be the next focus after the focused View
